I make a lot of fleece blankets and I don't take the time to "quilt" or stitch them at all to hold them together.
I use the entire width of the fabric and decide on the length. They are stitched right sides together the length of the blanket. Then I turn it inside out and stitch approx. 3/4" away from the stitching line. Then I mark the open ends approx. 4" up and stitch across. Using a rotary cutter, I make 1" fringe. I have not ever stitched them together except on the long sides. They hold up amazingly well with no slippage. My kids each have several, my grandson has several. I keep them in our RV, we have several in our living room. They make great gifts. I've even made them for our dogs. Since these fleece blankets get a lot of wear and tear and washing and drying, they really hold up and are very warm. Hope this helped.
